INTRODUCTION
The InFocus® LP340™ and LP350™ multimedia projectors are 
specifically designed for multipurpose use. They generate crisp, 
clear images using Digital Light Processing™ (DLP) technology, 
and feature an M1-DA connector for easy, built-in digital/analog 
and USB connectivity. They are easy to connect, easy to use, easy 
to transport, and easy to maintain. The LP340 has native SVGA 
800x600 resolution, the LP350 has XGA 1024x768 resolution. The 
user interfaces of the two products are identical; information in 
this user’s guide applies to both products. 
Image Resolution

The SVGA resolution of the LP340’s projected image is 800x600. 
The projector cannot compress screen resolutions above 
1024x768. If your computer’s screen resolution is higher than 
1024x768, reset it to a lower resolution before you connect the 
projector.
LP350

projector.

expands 640x480 images to 
800x600. You can display these 
images at their native resolutions 
by turning off the Auto Resize fea-
ture. See “Resize” on page 24 for 
more information.
NOTE: The LP350 automatically 
expands 640x480 and 800x600 
images to 1024x768. You can dis-

resolutions by turning off the Auto 
Resize feature. See “Resize” on
